6.5.2.5 Quality Assurance Procedures to be Supported
● Quality of Service (QoS) procedures in accordance with IEEE 802.1q (layer 2)
● Type of Service (ToS) in accordance with RFC 791 (layer 3), packet prioritization
● Differentiated Services (DiffServ - DS) procedure in accordance with RFC 2474 (layer 3)
6.5.2.6 Maximum Package Losses
A maximum packet loss of 3% is tolerated. The reduced voice quality associated with packet
loss is greater for G.723.1 and G.729 than for G.711.
6.5.2.7 Minimization of Broadcast/Multicast Traffic
In accordance with the rules of good network design, broadcast/multicast traffic should be kept
to a minimum. The use of routers/layer 3 switches to structure the network (for example VPM)
or the use of layer 2 switches can help detect multicasting traffic.
6.5.2.8 Requirements for Standalone Systems:
● Switched or shared LAN (Ethernet IEE 802.3/802.3 u) with 10 or 100 Mbps
● Pure Microsoft TCP/IP network (not a Novell network with IPX/SPX)
● Fixed IP addresses (no DHCP)
● The bandwidth required for transferring additional services (CDR and ACD/TAPI informa-
tion) must be taken into account. If the bandwidth is sufficient, a second protocol (e.g. No-
vell) may be possible.
6.5.2.9 Adaptation of QoS Classes to Oscar
Standardization according to the “HiPath QoS Strategy” involves adjusting the assignment of
QoS classes on HG 1500 and in WBM.
